AstralPool Sand

Sand is the filtering medium inside the pool filter. When the water enters the filter, it passes through the sand and leaves the particles suspended in it. Good maintenance is important to ensure the quality of filtration. There are different grain sizes of sand and new filter media such as glass.

Without a doubt, sand or silica are the most commonly used materials in domestic swimming pools. Sand retains dirt from the water as it passes through the pores formed by its irregular shape. As a disadvantage, sand requires maintenance because channels can form when it is used, causing water to flow directly into the pool without being filtered. Another disadvantage is the ability of sand to retain bacteria and microorganisms, which can cause them to proliferate inside the filter.
